Understanding Stucco Lath
Stucco lath serves as the foundation for stucco applications, providing a sturdy base for the materials that follow. As explained on thestuccoguy.com, lath is crucial for waterproofing walls and ensuring that the stucco adheres properly. Typically made from metal, wire, or foam, lath is installed directly onto the wall framing, creating a secure structure for the stucco mix to grip onto.
Types of Stucco Lath
Metal Lath
Metal lath is the most common type used in stucco applications. It is typically made from galvanized steel and is known for its durability and strength. Metal lath comes in various gauges and styles, including diamond mesh and square mesh. The Home Depot offers a variety of metal lath options, making it easily accessible for contractors and DIY enthusiasts.
Wire Lath
Wire lath, often referred to as chicken wire, is another popular choice for stucco applications. As noted in thestuccoguy.com, this type of lath is lightweight and flexible, allowing for easy installation in various shapes and sizes. It is especially useful in areas where a more customized application is needed.
Foam Lath
Foam lath, typically constructed from Expanded Polystyrene (EPS), is ideal for insulated stucco systems. It provides excellent thermal performance and moisture resistance. Atlas Stucco highlights the energy-efficient benefits of foam lath, making it a popular choice for modern construction projects.
Plastic Lath
Plastic lath is a lighter alternative to metal and wire options. It is moisture-resistant and easy to handle, making it a suitable choice for lightweight applications. While not as strong as metal lath, its ease of use and resistance to rust make it a viable option for certain stucco projects.
Wood Lath
Wood lath is a traditional method of applying stucco that has been used for centuries. It consists of thin strips of wood attached to the wall, providing a base for stucco. While it is not as commonly used today, it can still be found in historical restorations and certain architectural styles.
The Importance of Lathing in the Stucco Process
Waterproofing
One of the primary functions of stucco lath is to protect the underlying structure from moisture intrusion. As detailed on stuccoboy.com, a properly installed lath system creates a barrier that prevents water from reaching the framing of the home, thus reducing the risk of mold and water damage.
Structural Support
Stucco lath acts as a support system for the stucco itself. It ensures that the stucco mix adheres properly and provides a solid foundation for the finished product. This is particularly vital in three-coat systems, where the lath plays a crucial role in the overall integrity of the stucco finish.
Compatibility with Different Stucco Systems
Stucco lath is compatible with various stucco application systems, including one-coat and three-coat methods. Each system has its own requirements for lath installation, and understanding these differences is essential for achieving optimal results.
Installation Techniques
Proper installation of stucco lath is critical for ensuring a successful stucco application. Amicoglobal.com outlines several steps involved in the lathing process, including the use of weep screeds, waterproofing paper, and the correct fastening of lath to the wall.
